FESTOONING MACHINE FOR CARRYING PAPER AND THE LIKE.

Application filed July 16, 1924. Serial no. 726,373.

To all whom it may concern:

Be it known that I, JosEPH H. MILLER, a citizen of the United States, residing at Stevens Point, in the county of Portage and State of Wisconsin, have invented certain new and useful Improvements in Festooning Machines for Carrying Paper and the like; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to apparatus and method for handling wet paper in web or continuous form while hung up in festoons in passing through the drying loft and has for its object to prevent so-c-alled' stick marks in the material being dried. These marks are caused by the paper resting, or being carried on the sticks in the same position during the time of drying and are in the nature of a permanent setin the paper.

In accordance with the present invention there is provided an apparatus which will permit the different portions of the paper being alternately supported on the stick while the paper is being progressed through the drying loft thus permitting each portion to dry normally during the interval when not in contact with the supporting stick and hence preventing the paper from acquiring permanent poleor stick marks. The apparatus is so constructed that the poles supporting the paper are each periodically turned in unison in a given direction and periodically reversed. The reversal of the direction of rotation of the sticks at intervals keeps the paper suspended in substantially the same relative position with respect to the travelling carrier of which the sticks 0r poles are a part.

In the ordinary festoon system of drying, the paper or other material is carried through the drying room or tunnel by being hung from sticks or poles in loops or festoons of approximately equal length. 'For difl'erent classes and grades of material the length of loop or festoon is ordinarily some length between one foot and ten feet from top to bottom. The poles or sticks carrying the paper or other material are caused to move throughthe drying room or tunnel, either by being carried on a' travelling chain or chains, or by being pushed along a fixed track by fingers attached to a reciprocating bar, which causes the fingers to push the sticks forward a certain distance, moves back to its original position, then moves for ward again, and so on. My improvement may be adapted to either of these systems of carrying the sticks.

The various features of novelty and invention will appear from the detailed description taken in connection with the accompanying two sheets of drawings formin part of this specification.

iteferring to the drawings, F ig. l is a perspectiveview, in more or'less diagrammatic form, showing the paper supported in festoons on the improved sticks.

Fig. 2 is an enlarged vertical sectional view through one side of the frame on which the sticks are supported. I Fig. 3 is a section taken on line 33 of ig. 2. Y F Fig-. 4 is a section taken on line 44 of Fig. 5 is an elevation of one end of the improved sticks.

Fig. 6 is a group of three diagrammatic views to illustrate the different positions of the sticks with respect to the paper; and

Fig. 7 is a perspective view of-a modified form of the means for imparting turning movement to the sticks.

In Figs. 1 and 6, numerall indicates the paper or other material to be dried. The paper is shown as hung in festoons on sticks or poles of special form, thepoles being generally indicated by S. As shown, each pole comprisesa pair of round rods 2 and 3, maintained in relatively fixed relation by having both their adjacent ends secured to spacing blocks 4 in any suitable manner.

The ends of the poles S are provided with shafts 5 on which are mounted turnable bearing blocks 6, the shafts being suitably anchored in thespacing blocks 4. It will be understood that the axes of the shafts 5 are in alinement, and are midway between the pole rods 2, 3.

The machine frame includes a plurality of yokes having arms 10 and 11 to which are secured T-iron rails 12 a-nd13. The Webs of these rails are vertically disposed and on one side of the same are disposed guide rails 7 and 8 between which is slidabiy Sreceived the bearing block 6 of the po e The paper is usually progressed through the drying loft or tunnel in a. step-by-step movement and to that end the poles are pushed along periodically. ,Ajconvenient form" of" pusher meehanism includes trans versely extending bars 16 connected by rails 18 which ride on rollers '17 mounted on'the' to slide over and drop behind the beariugblocks 6 as thepusher bar 16 is moved back and forth byany suitable mechanism not shown. It will be understood that the poles S will be'n'ioved' forwardin unison with the I rod poles pusher" bars 16 but will remain stationary on the return stroke of the'pusher bars; In place of pusher bars chain's" which periodically progress may be employed;

Means are providedto cause the doubleand then in the opposite direction to support the paper first on one rod'and thenon the other; as the poles are pushedalon'g.

' Referringto Fig-., 6; the upper figure of the group showsthe thepaper while the lowerfigure shows the paper supported on the rod 3. The intermediate figure shows'how the paper is trans erred-from one rod to the'othergthe rotation of the pole as a whole being counterclockwise" in these views. The'tr'al'isferlof the paper from one rod to another is efi'e'cted during the periodthe' ole is being pushed along. With. respect'tofFi'g. 6the next tran'slatory movement of the p olewill :cause the pole to'turn. in a clockwisedir'ectioniwher'eloy the rod 2will again support the paper in approximately the same'place as before; as willn'owbe readily understoodi The novel means for imparting alternate turning movement tothe double-rod pole will now be described. Non turnably afliired to the pole, preferablyat' each end thereof,

' is'a round wheel ordisk 27; the same'being erence to Fig.

eccentrically positioned withrespect'to the shaft5. Mounted on the T-irons' 12 and 13 are two series ofupper and lower cam blocks 26 and 25;arranged' in staggered relation. Through the"zigzag pathf formed by these cam blocks the disk wheel "27 is designed to move,,-the action being such that the wheel is swung or turne'd'one half revolution in passing through the gateway 28 formed" by, the adj acent ends of the cam blocks; as will be readily 'apparentfloyref 3. The'diameter 'of thewheel or' disk 27 is such that it will -justp'ass through the space or gateway -28' eonstituted by the opposite b'locks 25 and 26. In Figs.-2"and"3"the wheel is positioned over one of'the'lower cam blocks 25. Assumingfthat the sticks S are moving toward the right as viewed in Fig, 3,1the wheel will maintain its- 0 sition as shown in "full lines fin "Fig'gB until it engages the rounded 'end 29fof"the upper cam block whenit obviously 'mus'ttur'n in upon being S 'to rotate I first in one direction rod 2 as supporting adjacent-ends of the cam" a counterclockwise directionin order to pass through the gateway between the adjacent ends of said cam blocks 24 and 26, and such turning will be approximately onehalf revolution. In further explanation of the action, it" may be -st'ated'th'at the 'wheel forced against the rounded end 29 of the cani block is given more than a rolling motion as it contacts with the. rounded end or cam. surface 29 of thecam block; it is causedit-o swing or turn faster] than would the hee'l and the rounded surface- 0f the cam block 29 are therefore smooth in order to permit relative slidinga ction when the wheel engages with the, said rounded surface. The rotary movement imparted to the sticks S bym'eans of the wheel and can": blocks is suflicient to turn said sticks through one-half revolution; as" has already been explained in connection with Fig. 6.,

If the pole S were being' moved toward theleftas viewed in Fig. 3, it is clear that:

the pole would be turned in, a clockwise direction as the wheel'passed beneath the upper camblock 263 It will be further ap 'preciated that the arrangement is? such that turned first inone direction 1 andthe poleis then in the opposite'direction'asthe pole is pushed or moved along. Y

A modified form' of'means' forbbtainingrotation of'the stick 3 is shown in Fig; 7 In place of the eccentric wheel there may be providedfia pinion 30 and in place of the cam blocks the racks 82; the

racks being placed in the samere'lative po= sition' as the cam blocks. Itwill be apparent that as thestick-"Stravela'the gear or pinion will "mesh alternatively with the top and bottom racks, opposite 'rotational'mov'ementbeing given to the stick by 'theupper and lower racks.

From the above description it will be seen thatthere has been provided an apparatus for drying paper which will permit the paper to be supported at more thanone line of" support during its course of travel through the drying room or tunnel. As

already indicated pole marks'are-formed when thepaper is allowed to besupported on the pole without change of position." The present invention, inasmuch as it" pro vides 101" a change of supportingposition' between the paper and the polesjresultsiin the elimination,- or the practical elimination, ofthe pole marks such as occur 'in'ordin'ary drying apparatus;
